Abstract: The present invention relates to supplying a load either from a direct-current source or from an alternating-current source. The power unit, according to the invention, is characterized in that it consists of a single conversion unit (CV) having unidirectional semi-conductor power components forming switches (I1, I2, I3, I4) controlled in appropriate fashion by a logic control in such a manner as to ensure the functioning of the conversion unit (CV) either in a chopper mode, or in a rectifier mode when the load functions to draw power, or to ensure energy regeneration when the load functions in a generating mode. The present invention has application particularly for supplying direct-current motors used in dual-current railroad locomotives.

Abstract: ABSTRACT            Joining together two materials by a mechanical interlock resulting from "chips" at their interface is disclosed.  The chips, composed of one of the two materials to be joined or of a third material are partially embedded into the surface of the first material when that material is formed so as to form surfaces which "overhang" the first material. Thereafter, the second material is formed against the overhanging surfaces of the chips to establish the mechanical interlock.  This technique is particularly use-ful  in anchoring a dissimilar material to a polymeric material having poor bondability and/or a high melt temper-ature, for example fluoropolymers, as illustrated by the forming of a liner for a pump casing, or the like, by rotational molding. In that illustration, small particles and chips are distributed uniformly over the surface of an enclosed mold heated to melt the particles and fuse the chips thereto, and cooled to form a layer with the chips projecting therefrom so as to provide an interlock when a casing is formed against the liner. Other aspects of the present invention include the article of manufacture formed by the above method.

The container has a mouth surrounded by a rim, at least a portion of the exterior surface, including the rim, of the container having a film coating of thermoplastic polymer thereon.  The first step in sealing comprises substantially reducing the amount of contents' residue from the container rim.  A closure is then applied to the rim. This closure is comprised of a layered material, having a thermoplastic polymer layer and a metallic layer, the thermoplastic layer contacting the thermoplastic polymer coating on the container rim.  The thermoplastic polymer layer and the thermoplastic polymer coating consist essentially of mutually compatible polymeric materials.  The closure is then heated in contact with the rim, to heat seal the closure to the rim coating and to seal the contents hermetically within the glass container.

Title: Distributor for ice chips and flakes - delivering definite quantities into a receptacle
IPC: F25C5/20
Filed: 1972-02-16
Abstract: Distributor comprises a reservoir connected to a device for the prodn of the ice chips or flakes; it is fed with water from a source under a press. The base of the reservoir is provided with an inclined channel fitted with a conveyor screw, driven by a motor. A blade, driven by an independent motor is mounted in the lower part of the reservoir and keeps the chips in a fluid condition, without sticking together. The ice is thus guided to the channel from which it is conveyed to the outlet when it falls into the receptacle. A blade moves from a posn. in which it closes the outlet to a second posn in which the mechanism ejects a definite quantity of ice, by force, into the receptacle. The inclined conveyor prevents any drops of water, formed during periods of low consumption, from escaping from the outlet. In use, a glass is placed under the outlet where it presses on a control lever to close a circuit which starts the conveyor motor. A selector switch controls the running of the motor for two, three or four cycles for delivering different quantities of ice.
